In one and a preferred construction, as shown in Figs. 1 to '7inclusive, the upper end of the blade supporting and dispensing shaft 2bis provided with a thrust bearing plate 2i, which is suitably aiixedthereto so as to rotate therewith. This thrust bearing plate ZI bearsagainst the under face of the top ywall lI of the casing so as toprevent upward axial movement or displacement of the shaft 2li. Theupper end of the blade supporting and dispensing shaft 29 terminates inan axially extending journal portion 22 which is journaled in a bearingopening 23 with which the top wall I I of the casing is provided. Saidjournal stud portion 22 projects exteriorly from the top wall I I of thecasing, and xed upon the projecting end of the journal portion 22 is amanipulatable finger-piece or knob 2t, by means of which the bladesupporting and dispensing shaft 2E) can be rotated. The linger-piece orknob 2li bears against the outer surface of the casing top wall II, thusholding the shaft 2D against downward axial movement or displacementfrom its operative assembled relation to the casing top wall, andtherefore maintained in operative assembled disposition within thecasing interior.

Means is provided for limiting the direction of rotation of the bladesupporting and dispensing shaft 2u to one which will result indownfeeding movement therealong of the blades l5 supported thereby, andin successive discharge of the blades from the lower free end of saidshaft. If the screw-thread of the blade supporting and dispensing shaft2U is a right hand thread (as shown), this means is so arranged as topermit rotation of the shaft in counterclockwise direction, whilepreventing rotation thereof in the opposite or clockwise direction, Anillustrative form of means for so controlling the operative rotativemovement of the blade supporting and dispensing shaft 2e, as shown moreparticularly in Figs. 3, 6 and '7, comprises a detent member 25, whichis aiiixed to the upper end portion of the shaft 2i! so as to rotatetherewith, and so as to underlie the thrust bearing plate 2 I, detentmember 25 is formed to provide a substantially radially extending springarm 2b which terminates in an upstanding check-nosing 2l. The thrustbearing plate 2l is provided with an opening 28 to permit upwardextension of said check-nosing 2l therethrough and into a correspondingopening 29 provided in the casing top wall I I. The opening 29 is formedat one side to provide a perpendicular stop shoulder 35 which is adaptedto be normally abutted by said checknosing 2l, so as to stop the bladesupporting and dispensing shaft 2@ against movement in clockwisedirection. Said opening 29 is formed at its opposite side to provide adownwardly inclined cam portion 3l, which is operative to depress thecheck-nosing 2 so as to withdraw the latter, against the tension of thespring arm 26 from the opening 29, when said check-nosing is moved incounterclockwise direction, thus permitting rotation of the bladesupporting and dispensing shaft 20 in like counterclockwise direction.

The interior of the casing, although of a length substantiallycorresponding to the lengths of the blades I5, is of a width appreciablyin excess of the widths of the blades, so that the blades Said assupported within the casing, and as guided for downward movementtherethrough by means presently to be described, will be so disposedrelative to the casing side walls I2 that the sharpened cutting edges ofthe blades will be spaced away from said side walls and prevented frommaking injurious or dulling contact therewith.

Provided within the internal junctures of the side and end walls I2 andI3 of the casing are vertically disposed or perpendicular guide ribs 32,which are arranged to extend between the top wall I I and the openbottom or mouth of the casing. These guide ribs are of crosssectionalshape to respectively correspond to and engage within the respectivecorner notches le of the blades I5, and laterally opposed guide ribs arespaced apart correspondingly to the widths of the end portions I9 of theblades; all whereby the blades, although free to move bodily downn wardthrough the interior of the casing, are nevertheless held against unduelongitudinal and lateral shifting movements, and also against rotativemovement about the axis of the screwthreaded shaft 20 by which theplurality of said blades are supported in a stack or column formationwithin the casing interior.

The stack or column of blades l5, as suspended by the -blade supportingand dispensing shaft 223 within the casing, is so disposed that itslower end is spaced above the plane of the open bottom or mouth of thecasing, thus providing within the open bottom end of said casing a spaceor socket 33 for the reception of the head H of a safety razor R.,whereby the casing can be applied to the razor head so as to oppose thebottom-most blade of the stack or column of blades thereto, subject todischarge of said bottom-most blade, by operative manipulation of theblade supporting and dispensing shaft 2Q, for deposit upon and inassembled relation to the razor head. Within said space or socket 33,the guide ribs 32 are out away or recessed to provide razor head seatingshoulders or stops 34, the latter being upwardly offset from the planeof the open end or mouth of the casing.

Before applying the casing to the razor head H, the blade clamp-cap C ofthe razor is displaced from said head H, whereby the blade receiving topof the latter, together with the blade engaging projections P with whichthe head is provided, are exposed for reception of a blade I5. When thecasing is applied to the razor head H, the ends of the latter will beabutted against the shoulders or stops 35, so that by engagementtherewith and as straddled by reduced end portions 35 of the guide ribs32, which extend below the shoulders or stops 34, the razor head willnot only be disposed in a plane adjacently below and parallel to theface plane of the bottom-most blade I5 of the stack or column thereof,but also in longitudinally aligned relation to the latter so as todispose the blade engaging projections P of the razor head H in alignedrelation to the medial slot I6 of said blade.

After the casing has been operatively7 assembled with the razor head H,as above described, the bottom-most blade I5 of the contained stack orcolumn of blades can be discharged and dropped over the blade engagingprojections P and onto the razor head H by rotating the fingerpiece orknob 2d in counterclockwise direction one full revolution. Suchmanipulation of the iingerpiece or knob 2li rotates the thrust bearingplate 2i and detent member 25, so that the checknosing21`ofwthelatter-.rides out of .the opening... 29 of the'casingtop wall Il, andtravels. around beneath said top Wall unitil it is again broughtintoregistration with and so as to reenter saldi` opening 29,'thusindicating the completion of.. one full revolution of the finger-pieceor knob.`

The turning of thenger-piece or knob 24. one

fullrevolution causes.` the blade supportingand l dispensing shaft Z tomake a correspondingcfullf.

revolution, whereby the blades l-.ofthezstack or-columnthereof, asengaged by the screw-f thread of the shaft, `and as held againstrotative movement by the casing, are all caused to descend alongthefshaft a distance corresponding ,tor the pitch of the screw-threadthereof. Such downfeeding movement of the stack or column of bladescauses the bottom-most blade to feed offV from the lower free end of theshaft, and thus to be `released from the support of the screw-` thread.When the bottomemost blade 'is thus released, the same drops, bygravity, onto the razor head H and over the blade engaging projections Pthereof (see Fig. 5).

After a bladeis thus discharged from the casu ing onto the razor headH,.the` casing is removed from the latter, and'thereupon thebladeclampx-w ing cap C is applied in its operativeblade engagingrelation to the razor head. It `will belobviousf that-theseoperationscan all be performedwithl out necessity for the operator totonchy a blade at any timaand consequently all risklof cutting the`lingers is positively eliminated. The above described blade dispensingoperations maybe repeated until the last blade ofthe stack or columnthereof has been discharged and the casing is empty.

Referring to Figs. 8 and 9, there isshown thereby a modified`arrangement for mounting` and actuating the screw-threaded bladesupporting and dispensing shaft 2@ of the magazine: In" this modifiedconstruction, the external iinger-` piece or knob 24 Ais eliminated,andthe thrust bearing plate is modified so as to serve both as `ajournaling support for the shaft 2&3 as well as a" means by which thelatter can be actuated. To this end a circular bearing plate 36 of adiam'- eter exceeding the width of the casingispro# vided. Said circularbearingy plate 35 is rotatably supported in bearing openings 3l.with'which" the side walls i2 of the casing are provided,` and. whichare. conformable toopposite peripheral portions of said bearing plate.The bearing openings tl underlie the top wall ll of the casing, so` asto support said Abearing plate 35i `contiguous to the inner or underface of said casing `topwall. The blade supporting and dispensingshaft'Zllis suitably aihxed by-its upper end .to said 'bearing` plate3E, so.as to depend from the latter, and' so as to rotate therewith.Aflixed tothe blade` supporting and dispensing shaft QM `so as to`underlie the bearing plate 35, is the detent mem--` ber 25 having thespring` arm 25 "which termi nates in the check-nosing 2l. Saidchecklnosing.. 2l projects upwardly through the bearingplate forreleasable engagement in theopening 29"of the casing top Wall ll, all inthe same manner andforthesame purposes as already setforth.. inconnection `with the heretofore first described form of the bladeholding and dispensingdevice.A It will be obvious, that by engaging..opposite exteriorly projecting peripheral portions of `the bearingplate-35,. rotative movement in proper. direction maybe imparted thereto,wherebyf to.. rotate the blade supporting and dispensing shaft 20 .iforwthe blade discharging Aoperations -above .i

described..

As` shown Uin Fig. 10, removable cover means maybe provided, ifdesired,`for closing the open. Ybottom end or mouth of the magazine casing It.will be understood -thatlvariation in the detail construction andarrangementof ther-parts i ofthe device, and inits blade `holdingcapacity,
